As shown in Figure 1, vacuum insulation panel 1 comprises core 10, sorbent 11 and sheathing material 12.
Sorbent 11 is used for keeping for a long time vacuum.Sorbent 11 comprises adsorbent and/or getter.The calcium oxide (CaO) that is used for absorbing moisture is applied to sorbent 11.
To shown in Figure 4, core 10 is formed by the group (lump) of the fiber (hereinafter, glass fibre 20) that comprises glass wool (Fig. 3) and/or glass fibre (Fig. 4) such as Fig. 2.
Hereinafter, with reference to Fig. 5 a to Fig. 6 the technique of using glass fibre 20 to make core 10 is described.
The group of glass fibre 20 is prepared as so that some root glass fibre 20 mutually twines or mutually intersects, and wherein is formed with hollow portion 21 in every fiber.
The group of glass fibre 20 can be with being selected from hot-pressing method, needle punching and making with at least a method in the wet method of the water of admixture and tackiness agent.
When using hot-pressing method, the group of glass fibre 20 can followingly make.Group at glass fibre 20 is heated under the state of a temperature, press the group of (P) glass fibre 20, glass fibre 20 is softening to the not reformed degree of the sectional shape of glass fibre 20 (that is, glass fibre 20 temperature that begins to be out of shape a little by gravity or glass fibre 20 are out of shape by applying force to up and down pressing of glass fibre 20 temperature) in this temperature.
Subsequently, the group of the glass fibre 20 of the thermal distortion by pressing cools off by process for cooling.As a result, the group of glass fibre 20 loses the elasticity before the pressurization, namely by plastic deformation, has core 10 by the shape (that is, plate shape) of pressing formation with formation.
The core 10 that is formed by the group of glass fibre 20 keeps being plate shape, and not be used in the additional adhesives between each root fiber.
In addition, the conduction of the heat of glass fibre 20 minimizes by the hollow portion 21 that is formed in the glass fibre 20, thereby improves thermal conductivity.
The core 10 that forms as mentioned above is inserted in the sheathing material 12 of bag shape, as shown in Figure 6.
Subsequently, reduce pressure under the vacuum of the inside of sheathing material 12 in the underpressure chamber, so that sheathing material 12 has 1 * 10
-1Torr or lower internal pressure, the opening 12a of sheathing material 12 is sealed airtightly by thermal weld, thereby forms high-performance vacuum insulation panel 1.
Like this, and compare when adopting traditional non-hollow glass fibre to make vacuum insulation panel, low vacuum treatment is 1 * 10
-1Torr or lower pressure carry out, and also boost productivity thus thereby reduce manufacturing time.
As shown in Figure 7, thus glass fibre 30 can have hollow portion 31 and be formed on the hole (pore) 32 that its excircle place is communicated with hollow portion 31 according to another embodiment of the present invention.
A plurality of holes 32 of glass fibre 30 can be irregularly formed and can be of different sizes 32a, 32b and 32c.
The glass fibre 30 that use has hole 32 and a hollow portion 31 is made the method for cores 10 and is used core 10 to make that glass fibre that the method for vacuum insulation panels 1 and the use of describing before have hollow portion 21 is made the method for core 10 and the method for the use core 10 manufacturing vacuum insulation panels 1 described before is identical, therefore, will omit its detailed description.
In addition, the surface of glass fibre 30 is unevenness owing to being formed on hole 32 in the glass fibre 30, and the hole 32 of glass fibre 30 minimizes the heat transmission that the conduction by glass fibre 30 causes with hollow portion 31, thus the optimization heat transference efficiency.
Hereinafter, with reference to Fig. 9 the refrigerator 100 that wherein is equipped with according to the vacuum insulation panel 1 of the embodiment of the invention is described.
The storeroom 111 that is used for storage food is provided at the main body that is defined by roof 100a, diapire 100b, sidewall and rear wall 100c.
Although do not illustrate, storeroom 111 is separated at the cold storage room of frozen state storage food, stores the refrigerating chamber of food, vegetable compartment and the ice making compartment of storage vegetables at freezing state.
Vaporizer (not shown) for generation of cold air is installed in rear wall 100c.Machine room (machinery compartment) 112 is provided at the lower rear portion of the main body of refrigerator 100.The electricity parts such as compressor, are installed in the machine room 112.
Stabilizer F such as polyurethane, is filled in the space (vacuum insulation panel 1 being set in those positions) of definition around the external plates 110a of roof 100a and diapire 100b, sidewall, rear wall 100c and door 110, with fixing vacuum insulation panel 1.
Therefore, be arranged on the vacuum insulation panel 1 maximum heat transfer efficient that has simultaneously small volume in the insulating unit 120 of refrigerator 100, thereby based on the heat-shielding performance of improving refrigerator 100 than the high heat-shielding performance of stabilizer F.
Obvious from the above description, be formed on hollow portion in the core (that is, glass fibre) and minimize heat transmission by glass fibre, thus the optimization heat transference efficiency.
In addition, the hole of the excircle of the surface of glass fibre by being formed on glass fibre and unevenness.Therefore, thereby the contact between each root glass fibre is reduced the heat transmission that minimizes by glass fibre, thus the optimization heat transference efficiency.
In addition, because the conduction of the heat of glass fibre is lower than traditional glass fibre, so even by the rough vacuum decompression, also made Performance Ratio and used the vacuum insulation panel of the vacuum heat-insulation plate hight of traditional non-hollow glass fibre manufacturing, thereby improved the manufacturing cycle.
Although illustrated and described several embodiments of the present invention, it will be understood by those skilled in the art that and can change in these embodiments, and do not break away from principle of the present invention and spirit, scope of the present invention is limited by claims and equivalent thereof.
